The henry family drove 276.5 miles on the family vaction. they used 7.9 gallons of gas. how many miles per gallon of gas did they get on the trip

To solve this problem you would have to write 276.5 over 7.9 and divide the numerator and denominator by 7.9 since you want miles per gallon (it should have a denominator of 1 after you divide). When you do this you will get 35, so the Henry family got 35 miles per gallon of gas on the trip.

The answer is 41.7 because 1.39 times 30 is 41.7
